Change ags launcher to be full launcher.

[BeyondMagic]

Launcher must be able to:

• enable/disable dinit services (this can be just predefined commands, but with a check before showing which one)
• manage ags widgets (can be predefined commands).
• run predefined commands:
  • extensions?
  • get dictionary from word, like dict.nu
  • list emoji, kaomojis
• calculate mathematical expressions using Qalculate:
  • set up own service (libcalculate running on background with AGS and only read commands when sent to it)
• run desktop apps.
• Make schema.
• Change from JSON to TOML with additional script.
